I inherited this case from another dentist who placed and restored the two maxillary central incisors. Implants were placed 8/30/17 and are 3.3x13mm. They are 1mm sub-crestal and were placed using a surgical guide. Basically when the doctor placed the cement retained crowns he told the patient that the gingiva would mature and fill in over the next year (That was in 12/20/17).
I last saw the patient in April of 2018. Patient is very concerned about the black triangles between 11 and 21 implants.
I am just wondering what is the best way to proceed? I cannot change where the implants were placed. But I could try doing a connective tissue graft or adding pink porcelain to the crowns but I feel that would be a really unaesthetic way to solve the problem. Thoughts?
